Orbital cellulitis and abscess have been described in the literature as complication that usually occur secondary to infection in the maxillary, ethmoidal, and frontal sinuses. If left untreated, it can lead to blindness, cavernous sinus thrombosis, meningitis, or cerebral abscess. Orbital fractures are a common sequela of blunt orbital trauma, but are only rarely associated with orbital cellulitis. So, the authors present rare orbital cellulitis after orbital blow-out fracture. A 55-year-old Asian complains of severe orbital swelling and pain on the left side. These symptoms had started 2 days earlier and worsened within the 24 hours before hospital admission resulting in visual disturbances such as diplopia and photophobia. Contrast-enhanced computed tomography scan showed considerable soft tissue swelling and abscess formation on the left side. Patient was subjected to surgical drainage under general anesthesia in the operation room. In this case, the postoperative period was uneventful and the rapid improvement of symptoms was remarkable. In conclusion, the abscess of the orbit is a surgical emergency in patients whose impairment of vision or ocular symptoms cannot be controlled with medical therapy using antibiotics. In our case, orbital cellulitis can occur after blunt orbital trauma without predisposing sinusitis. Early and prompt diagnosis and surgical drainage before severe loss of visual acuity rescue or recover the vision in case of orbital cellulitis.
BACKGROUND This report describes and discusses recurrent intramuscular lipoma (IML) of the extensor pollicis brevis (EPB). An IML usually occurs in a large muscle of the limb or torso. Recurrence of IML is rare. Recurrent IMLs, especially those with unclear boundaries, necessitate complete excision. Several cases of IML in the hand have been reported. However, recurrent IML appearing along the muscle and tendon of EPB on wrist and forearm has not been reported yet. CASE SUMMARY In this report, the authors describe clinical and histopathological features of recurrent IML at EPB. A 42-year-old Asian woman presented with a slow-growing lump in her right forearm and wrist area six months ago. The patient had a history of surgery for a lipoma of the right forearm one year ago with a scar of 6 cm on the right forearm. magnetic resonance imaging confirmed that the lipomatous mass, which had attenuation similar to subcutaneous fat, had invaded the muscle layer of EPB. Excision and biopsy were performed under general anesthesia. On histological examination, it was identified as an IML showing mature adipocytes and skeletal muscle fibers. Therefore, surgery was terminated without further resection. No recurrence occurred during a follow-up of five years after surgery. CONCLUSION Recurrent IML in the wrist must be examined to differentiate it from sarcoma. Damage to surrounding tissues should be minimized during excision.
This report describes and discusses the clinical investigations available for the investigation of intraoral fatty tumors of the chin, with a focus on lipomas. Lipomas are relatively uncommon tumors in the oral cavity; only 1% to 4% of cases occur at this site. The presence of lipoma in the head and neck area may raise problems in surgical resection. Treatment of lipoma needs wide excision to reduce recurrence. But there are important structures on mental foramen, especially mental nerve. So careful dissection must be done to avoid nerve injury. Importantly, the development of sarcomatous change within the lipoma cannot be ruled out at imaging and requires a histologic specimen. Because of the histologic similarity between normal adipose tissue and lipoma, accurate clinical and surgical information is very important in making a definitive diagnosis. Thus, a clinician sending a surgical specimen for microscopic analysis must provide the oral pathologist with all available clinical and surgical information. The treatment of oral lipomas, including all the histologic variants, is simple surgical excision. No recurrence is observed. Although the growth of oral lipomas is usually limited, they can reach great dimensions, interfering with speech and mastication and reinforcing the need for excision. In this study, the authors describe the clinical and histopathologic features of symptomatic 2 patients of oral lipomas.
Dermoid cysts are benign developmental anomalies that occurred as a result of the sequestration of the skin along the lines of embryonic closure. Those occurring in the cervicofacial region are uncommon, accounting for about 7% of all dermoids and its presence in postauricular region is further exceptionally rare. A healthy 19-year-old Asian boy presented with a unilateral postauricular cyst that had been present since childhood without any symptom. The computed tomography scan revealed an encapsulated tumor with no intracranial extension. Histological examination of a biopsy taken from the lesion revealed a unilocular cyst found in the deep dermis and subcutaneous tissue. Multinuclear giant cells and fragments of hair shaft are infiltrated in the cystic wall. Some keratin materials are seen in the intracystic area. However, the lining cells are not found. These histologic findings were suggested of the dermoid cyst. Patients with postauricular dermoid cysts usually seek medical advice for the cosmetic reasons because of the embarrassing look of the prominent unilateral or bilateral ears. The treatment of postauricular dermoid cyst is complete surgical excision of the cyst wall. Incomplete removal may result in recurrence or infection; thus, complete surgical excision is necessary. The prognosis is excellent without further complication.
